Ah, but the ToS I agreed to didn't state it.. they even admitted it wasn't clear and then unilaterally revised it.
And yes, I agree businesses must abide by the ToS, it would be too much of a business risk not to.. but individual users, using for their own purpose can make their own choice.
An individual choosing to not abide by their unfair ToS is perfectly reasonable and doesn't make them unserious or immature people, and it's pretty weak to make it an ad hominem attack.
But if you think their reasoning is solely that opencode has poor caching, then the solution is to make it chew through the quota quicker (which i think it already does), or provide guidance on how to do it better. The arms race of trying to block it will be a war they will eventually lose.
